这就是我运行 junit 测试时发生的情况......
Another CacheManager with same name 'cacheManager' already exists in the same VM. Please
provide unique names for each CacheManager in the config or do one of following:
1. Use one of the CacheManager.create() static factory methods to reuse same
CacheManager with same name or create one if necessary
2. Shutdown the earlier cacheManager before creating new one with same name.
The source of the existing CacheManager is:
DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ]
异常背后的原因是什么。可以同时运行 1 个以上的 cacheManager 吗？
这就是我使用 Sping 3.1.1 配置 cachManager 的方式。它明确地将 cacheManager 的范围设置为“singleton”
<ehcache:annotation-driven />
<bean
id="cacheManager"
class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
scope="singleton"
/>
ehcache.xml 看起来像
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
updateCheck="false"
maxBytesLocalHeap="100M"
name="cacheManager"
>
....
</ehcache>
最后我的课
@Component
public class BookingCache implements CacheWrapper<String, BookingUIBean> {
@Autowired
private CacheManager ehCacheManager;
....
}
我很确定我在我的代码库中只处理一个 cacheManager。其他东西可能正在运行第 n 个实例。
